Yes but LUKS header does not have attribute for storing IV offset. New format will allow it, so we can think about using the new header as "a generic key storage". (In fact if there is enough space on device we can convert the device metadata in-place. But that's future...) > Currently,LUKS API does not have an option to set IV offset and my problem would > be solved if the API is introduced. I really do not want to workaround problems in other software by introducing hacks in current version of LUKS. If you really want this, you can use existing API (open LUKS device/header, get volume key, open device again in PLAIN mode and use the parameters). Should be few lines of code.
